#1177 TightVNC 2.5.2 + DF Mirage and Dual Monitors


The viewer does not display correctly when using version 2.5.2 and DF Mirage drivers on a system setup with dual monitors where the "main display" is set to the 2nd monitor and extended onto the 1st monitor. Only one monitor is displayed in the viewer, the other is a black screen. When you try to interact with what's displayed it doesn't do anything, but if you click in the area where the other monitor should display (the black screen) it interacts with the other monitor.

Un-installing the DF Mirage driver corrects the problem. And also if the display settings are setup such that the "Main display" is on monitor 1 it works as well.

    I upgraded from TightVNC 2.0.2 so I didn't have the DF Mirage driver installed and I still found this problem. "Fortunately", I after I installed and then uninstalled the DF Mirage driver as a workaround the issue went away.

    I can confirm this bug.

    On a 3 monitor setup, VNC is showing monitor #2 where #1 should be, monitor #3 where monitor #2 should be, and a black screen where monitor #3 should be.

    However the mouse is in the correct place. So you are controlling monitor #2, but seeing monitor #1, for example.

    Uninstalling DF Mirage driver corrects the problem. (Unchecking "use mirror driver if available" does not correct the problem).
